Description

A communication method and related products

This application claims the priority of a Chinese patent application with application number 202111176882.3 and application title "A Communication Method and Related Products" filed with the China Patent Office on October 09, 2021, the entire contents of which are hereby incorporated by reference in this application .

technical field

This application relates to the field of electronic technology, in particular to a communication method and related products.

Background technique

With the development of technology and the progress of society, in order to provide higher service rates, the 3rd Generation Partnership Project 3GPP ( ^3rd Generation Partnership Project) introduced the carrier aggregation (CarrierAggregation, referred to as CA) function, multiple continuous or discontinuous components Carriers (Component Carrier, referred to as CC) are aggregated into larger bandwidth, and the dual connectivity (DualConnectivity) function makes full use of the resources and advantages of different carriers and different standards to improve the user's uplink and downlink peak rate experience.

In the existing network architecture, in the CA scenario, both the control plane and the user plane are carried on the primary carrier cell PCC, and then the data of the user plane is offloaded to the secondary carrier cell SCC through the RLC layer of the PCC for transmission. Similarly, in the CA scenario, both uplink and downlink are carried on the same carrier cell (PCC or SCC). At the same time, in the dual connectivity DC (DualConnectivity) scenario, the uplink and downlink are carried on the same carrier group (main carrier group MCG or secondary carrier group SCG).

In such a multi-carrier scenario (CA or DC), the strong coupling between the control plane and the user plane, uplink and downlink (carried on the same carrier), will lead to a large difference in carrier capability, such as the carrier capability of SCC. When the carrier capability of the PCC is limited, the SCC can carry most of the traffic at this time, so the traffic carried on the user plane of the PCC needs to be offloaded to the SCC through the RLC layer of the PCC. The offloading process not only adds additional paths and causes path delays, Moreover, this path will also limit the diverted traffic, so that resources cannot be maximized according to business demands.

Contents of the invention

The present application provides a communication method and related products, so as to reduce the waste of communication resources and improve the utilization rate of communication resources.

In the first aspect, the embodiment of the present application provides a communication method, which is characterized in that it is applied to network equipment, and the method includes: performing the transmission of the first type of data through the primary carrier cell PCC, and performing the second type of data transmission through the secondary carrier cell SCC Transmission of two types of data; wherein, the first type of data includes control plane data, the second type of data includes user plane data, or the first type of data includes uplink data, and the second type of data includes downlink data , or the first type of data includes downlink data, and the second type of data includes uplink data.

The embodiment of this application is applied to the CA scenario of carrier aggregation, and adopts the structure of separating the user plane and the control plane, uplink and downlink, and the original control plane and user plane, uplink and downlink can only be carried on the same carrier, and become the control plane On the PCC, the user plane is on the SCC, or the uplink is on the PCC and the downlink is on the SCC, or the downlink is on the PCC and the uplink is on the SCC. Different from the architecture in the prior art, the control plane and the user plane, or the uplink and downlink can only be carried on the same carrier, while the embodiment of the present application can not only carry the user plane and the control plane on different carriers respectively, for example, control The plane is on the PCC, and the user plane is on the SCC. In this way, when the carrier capacity of the SCC is greater than that of the PCC, the data exceeding the capacity of the PCC needs to be sent by the RLC layer of the PCC, passed through the transmission channel, and then sent by the MAC layer of the SCC. For the terminal, an additional path delay is introduced; in addition, if the transmission channel is limited, the capabilities of the SCC cannot be fully utilized, wasting resources; and the uplink and downlink can be deployed separately, so that the uplink and downlink can respectively select the optimal performance Carrier deployment. For example, the downlink with a large amount of traffic needs to be deployed on the SCC with large bandwidth, but the uplink capability of the SCC is weak, but the uplink capability of the PCC is strong, and the downlink capability is weak. There is always one party whose performance suffers. Therefore, using the separation architecture provided by the embodiment of the present application, the uplink and downlink can respectively select carriers with better performance for deployment. To sum up, through the communication method provided by the embodiment of the present application, the user plane and the control plane, or uplink and downlink, can be deployed on different carriers, so that the resources and advantages of different carriers can be fully utilized to maximize resources. Utilize efficiently to improve the service rate.

Or receive the third message through the RLC layer of the SCC, and use the third message to generate a fourth message, send a part of the fourth message to the MAC layer of the SCC, and send the fourth message to the MAC layer of the SCC. The other part of the four messages is sent to the MAC layer of the PCC. This separated architecture can make the user plane data directly reach the SCC from the core network, and be sent directly by the air interface of the SCC, avoiding roundabout paths and reducing the data transmission delay; at the same time, even if the data beyond the SCC capacity needs to be sent to the PCC, The capability of the PCC is small, and the required transmission bandwidth is also small, thus reducing the scenarios of limited transmission.

The occurrences of this phrase in various places in the specification are not necessarily all referring to the same embodiment, nor are separate or alternative embodiments mutually exclusive of other embodiments. It is understood explicitly and implicitly by those skilled in the art that the embodiments described herein can be combined with other embodiments.

The terms "component", "module", "system" and the like are used in this specification to refer to a computer-related entity, hardware, firmware, a combination of hardware and software, software, or software in execution. For example, a component may be, but is not limited to being, a process running on a processor, a processor, an object, an executable, a thread of execution, a program, and/or a computer. By way of illustration, both an application running on a computing device and the computing device can be components.

Communicate through local and/or remote processes.

Firstly, analyze and put forward the technical problem specifically to be solved in this application. With the development of technology and the progress of society, in order to provide higher service rates, 3GPP introduces the CA function, which aggregates multiple continuous or non-contiguous The resources and advantages of the standard improve the user's uplink and downlink peak rate experience. In the existing network architecture, in the CA scenario, both the control plane and the user plane are carried on the primary carrier cell PCC, and then the data of the user plane is offloaded to the secondary carrier cell SCC through the RLC layer of the PCC for transmission. Similarly, in the CA scenario, both uplink and downlink are carried on the same carrier cell (PCC or SCC). At the same time, in the DC scenario, both the uplink and downlink are carried on the same carrier group (main carrier group MCG or secondary carrier group SCG).

To sum up, the existing communication methods cannot meet the user's demand for uplink and downlink peak rates, and cause a lot of waste of resources. Therefore, the communication method provided in this application is used to solve the above technical problems.

In order to facilitate the understanding of the embodiments of the present application, the following exemplifies the scenarios where the communication method in this application is applied, which may include the following two scenarios:

Scenario 1, applied to the carrier aggregation CA scenario:

Carrier Aggregation CA was introduced in Release 10 of 3GPP. It aggregates multiple continuous or non-continuous carriers (ComponentCarrier, CC for short) into a larger bandwidth to meet the requirements of 3GPP. Please refer to FIG. 1 for details. FIG. 1 is a schematic diagram of a carrier aggregation system architecture provided by an embodiment of the present application. As shown in FIG. 1, the system architecture may include a terminal device 100, a network device 110, multiple different carriers F1, F2, F3, etc., NR. New air interface NR (New Radio) is a channel for establishing a wireless connection between terminal equipment and network equipment. F1, F2, F3, etc. represent different carriers. The terminal device 100 and the network device 110 aggregate multiple continuous or discontinuous carriers (F1, F2, F3, etc.) in the NR into a larger bandwidth for data transmission, which is called carrier aggregation process.

Scenario 2 applies to dual-connection DC scenarios:

The scenario of dual connection means that one terminal device maintains connection with two network devices. See FIG. 2 for details. FIG. 2 is a schematic diagram of a dual connectivity system architecture provided by an embodiment of the present application. As shown in FIG. 2 , the system architecture may include a terminal device 200 , a network device 210 , and a network device 220 . The terminal device 200 establishes connections with the network device 210 and the network device 220 respectively.

It can be understood that the above two application scenarios are only several exemplary implementations in the embodiments of the present application, and the application scenarios in the embodiments of the present application include but are not limited to the above application scenarios.

Based on the technical problems raised above and the corresponding application scenarios in this application, and to facilitate the understanding of the embodiments of the present application, the following first describes one of the network architectures on which the embodiments of the present application are based. Please refer to FIG. 3 . FIG. 3 is a structural diagram of a communication method provided by an embodiment of the present application. The technical methods of the embodiments of the present application may be specifically implemented in the system architecture shown in FIG. 3 or a similar system architecture. As shown in Figure 3, the system architecture may include core network equipment and network equipment, as shown in Figure 3, the method can be applied to the system architecture described in Figure 1 above, and the architecture in Figure 1 can be used for Support and execute step S301 of the method flow shown in FIG. 3 . The following description will be made from the network device side with reference to FIG. 3 . The method may include the following step S301.

Step S301: performing the transmission of the first type of data through the primary carrier cell PCC, and performing the transmission of the second type of data through the secondary carrier cell SCC.

Specifically, the first type of data includes control plane data, the second type of data includes user plane data, or the first type of data includes uplink data, the second type of data includes downlink data, or the second type of data includes downlink data One type of data includes downlink data, and the second type of data includes uplink data.

For example, the specific process in which the first type of data includes control plane data and the second type of data includes user plane data may include the following steps:

Please refer to FIG. 4 . FIG. 4 is a schematic flow diagram of separation of a user plane and a control plane provided by an embodiment of the present application. First, the PDCP layer 401 of the PCC receives data from the control plane of the core network, and then generates a first message through the PDCP layer of the PCC, and then sends the generated first message to the RLC layer 402 of the PCC. After receiving the first message, the RLC layer of the PCC uses the first message to generate a second message, and sends the second message to the MAC layer 403 of the PCC. Finally, the MAC layer sends the third message to the terminal device. At the same time, a third message is generated by the PDCP layer 404 of the SCC and sent to the RLC layer 405 of the SCC. Then the RLC layer of the SCC receives the third message, uses the third message to generate a fourth message, and sends it to the MAC layer 406 of the SCC. Or the third message is received by the RLC layer of the SCC, and a fourth message is generated by using the third message, and a part of the fourth message is sent to the MAC layer 406 of the SCC, and the Another part of the fourth message is sent to the MAC layer 403 of the PCC. Optionally, the above steps may also be applied to FIG. 3a, and FIG. 3a is a schematic flowchart of a communication method provided in an embodiment of the present application. The above process also applies to this system architecture.

The technical effect of using the above-mentioned transmission path can be seen in Figure 5a and Figure 5b. Figure 5a is an architecture diagram in which both the user plane and the control plane are deployed on the PCC provided by the embodiment of the present application. Figure 5a is the existing architecture, from the core Both the control plane CP and the user plane UP of the network 503 are deployed on the PCC501, so that the user plane can only offload data to the SCC502 and send it to the terminal device 500 through the RLC layer of the PCC. This leads to the fact that when the SCC can carry most of the traffic, but the data needs to be distributed through the PCC, which will introduce path delay and be easily limited by the transmission pipeline, resulting in the gain loss of CA. However, when the architecture provided by the embodiment of the present application is adopted, the deployment as shown in Figure 5b can be obtained. Fig. 5b is an architecture diagram in which the control plane is deployed on the PCC and the user plane is deployed on the SCC according to an embodiment of the present application. In FIG. 5 b , the control plane CP from the core network 503 is deployed on PCC501 , and the user plane UP is deployed on SCC502 .

With the traditional CA architecture as shown in Figure 5a, the bearer of the control plane and user plane can only be deployed on the PCC, and the data is distributed to the SCCMAC by the RLC of the PCC. If the SCC carrier capacity is greater than the PCC carrier capacity, the data beyond the PCC capacity needs to be sent by the PCCRLC, through the transmission channel, and then sent to the terminal through the SCCMAC, which introduces additional path delay; in addition, if the transmission channel is limited, the SCC Capabilities cannot be fully utilized, affecting user experience. After adopting the separation architecture in this application as shown in Figure 5b, the user plane can be carried on the SCC, and the data directly arrives at the SCC from the core network and is sent directly by the air interface of the SCC, avoiding roundabout paths and reducing data transmission delay; at the same time, even if the data exceeds Data with SCC capability needs to be sent to PCC. PCC has small capability and requires small transmission bandwidth, which reduces the scenario of limited transmission;

When the first type of data packet contains uplink data and the second type of data includes downlink data, the specific process may include the following steps:

Please refer to FIG. 6 . FIG. 6 is an architecture diagram in which the uplink is deployed on the PCC and the downlink is deployed on the SCC according to an embodiment of the present application. First, the first message is generated by the MAC layer 601 of the PCC or a part of the first message is generated by the MAC layer 601 of the PCC, and another part of the first message is generated by the MAC layer 606 of the SCC, and sent To the RLC layer 602 of the PCC; receive the first message through the RLC layer of the PCC, use the first message to generate a second message, and send it to the PDCP layer 603 of the PCC. Optionally, first, a third message is generated by the PDCP layer 604 of the SCC, and sent to the RLC layer 605 of the SCC; the third message is received by the RLC layer of the SCC, and the third message is used Generate a fourth message and send it to the MAC layer 606 of the SCC; or receive the third message through the RLC layer 605 of the SCC, and use the third message to generate a fourth message, and send the first A part of the fourth message is sent to the MAC layer 601 of the SCC, and another part of the fourth message is sent to the MAC layer 606 of the PCC.

When the downlink data of the first type data packet, the specific process of the second type data including uplink data may include the following steps:

Please refer to FIG. 7 . FIG. 7 is an architecture diagram in which the downlink is deployed on the PCC and the uplink is deployed on the SCC according to an embodiment of the present application. First, generate a first message through the PDCP layer 701 of the PCC, and send it to the RLC layer 702 of the PCC; receive the first message through the RLC layer of the PCC, and use the first message to generate a second message , and send it to the MAC layer 703 of the PCC. Or receive the first message through the RLC layer 702 of the PCC, and use the first message to generate a second message, send a part of the second message to the MAC layer 703 of the PCC, and send the message to the MAC layer 703 of the PCC. The other part of the second message is sent to the MAC layer 704 of the SCC. Optionally, generating a third message through the MAC layer 704 of the SCC or generating a part of the third message through the MAC layer of the SCC, and then generating another part of the third message through the MAC layer 703 of the PCC, And send it to the RLC layer 705 of the SCC; receive the third message through the RLC layer of the SCC, use the third message to generate a fourth message, and send it to the PDCP layer 706 of the SCC.

The technical effect of adopting the above-mentioned transmission path can be seen in Fig. 8a-Fig. 8d. Fig. 8a is an architecture diagram provided by the embodiment of the present application in which both the downlink and uplink are carried on the PCC/MCG. Fig. 8a is the existing architecture, the terminal device 800 Both uplink and downlink tasks are deployed on PCC/MCG801. Fig. 8b is an architecture diagram in which both the downlink and the uplink are carried on the SCC/SCG provided by the embodiment of the present application. Fig. 8b shows the existing architecture, and both the uplink and downlink tasks of the terminal device 800 are deployed on the SCC/SCG802. Fig. 8c is an architecture diagram in which the uplink is carried on the PCC/MCG and the downlink is carried on the SCC/SCG provided by the embodiment of the present application. Fig. 8c shows the architecture provided by the embodiment of the present application. The uplink of the terminal device 800 is deployed on the PCC/MCG801, and the downlink is deployed on the SCC/SCG802. Fig. 8d is an architecture diagram of an embodiment of the present application in which the downlink is carried on the PCC/MCG and the uplink is carried on the SCC/SCG. Fig. 8d is the architecture provided by the embodiment of the present application. The downlink of the terminal device 800 is deployed on the PCC/MCG801, and the uplink is deployed on the SCC/SCG802.

As can be seen from the above figure, in the traditional CA/DC architecture, the uplink and downlink can only be deployed on one carrier in a unified way. When the uplink and downlink capabilities of the carrier are not equal, and the uplink and downlink service requirements are inconsistent, conflicts will be caused in the uplink and downlink deployment, and the uplink and downlink cannot be deployed at the same time. Get the best performance. For example, in the combination of FDD and TDD, the downlink with heavy traffic needs to be deployed on TDD with large bandwidth, but the uplink capability of TDD is weak, and the uplink service needs to be deployed on FDD. The strong coupling of uplink and downlink deployment will always lead to the performance of one side being affected. damage. This application adopts the separate deployment of uplink and downlink, and the uplink and downlink can respectively select the carrier deployment with the best performance.

To sum up, the above steps are applied to the carrier aggregation CA scenario, and the architecture of separating the user plane and the control plane, uplink and downlink is adopted, and the original control plane and user plane, uplink and downlink can only be carried on the same carrier, and become a control The plane is on the PCC and the user plane is on the SCC, or the uplink is on the PCC and the downlink is on the SCC, or the downlink is on the PCC and the uplink is on the SCC. Different from the architecture in the prior art, the control plane and the user plane, or the uplink and downlink can only be carried on the same carrier, while the embodiment of the present application can not only carry the user plane and the control plane on different carriers respectively, for example, control The plane is on the PCC, and the user plane is on the SCC. In this way, when the carrier capacity of the SCC is greater than that of the PCC, the data exceeding the capacity of the PCC needs to be sent by the RLC layer of the PCC, passed through the transmission channel, and then sent by the MAC layer of the SCC. For the terminal, an additional path delay is introduced; in addition, if the transmission channel is limited, the capabilities of the SCC cannot be fully utilized, wasting resources; and the uplink and downlink can be deployed separately, so that the uplink and downlink can respectively select the optimal performance Carrier deployment. For example, the downlink with a large amount of traffic needs to be deployed on the SCC with large bandwidth, but the uplink capability of the SCC is weak, but the uplink capability of the PCC is strong, and the downlink capability is weak. There is always one party whose performance suffers. Therefore, using the separation architecture provided by the embodiment of the present application, the uplink and downlink can respectively select carriers with better performance for deployment. To sum up, through the communication method provided by the embodiment of the present application, the user plane and the control plane, or uplink and downlink, can be deployed on different carriers, so that the resources and advantages of different carriers can be fully utilized to maximize resources. Utilize efficiently to improve the service rate.
